“…In contrast, F. jenkinsi is found from salinities near zero to upper 20 (most between salinity of 6 and 12; Peterson et al 2003) but generally were abundant in salinity <16 (present findings) and Simpson and Gunter (1956) collected them in Texas from salinity ranging from 3.4-20.6 (mean=14.0). Finally, F. luciae are found in salinity ranging from 0.4-46 (Richards and Bailey 1967;Griffith 1974;Able et al 1983;Kneib 1984) and are most often collected in the higher end of the salinity range compared with F. jenkinsi, but use similar marsh habitat types.…”

“…Throughout its range F. luciae is considered rare, patchily distributed, and small in maximum size (Richards and Bailey 1967;Jorgenson 1969;Kneib 1978;Kneib 1984). This species also shares habitat with F. heteroclitus which is as euryhaline and as abundant in the Atlantic marshes as F. grandis is in the marshes of the nGOM (Kneib 1978;Kneib 1984).…”

“…These conditions were similar to those of F. luciae in the Atlantic coast marshes where they have been shown to prefer the upper parts of the marsh. F. luciae, however, also ranges into higher salinity conditions (Richards and Bailey 1967;Jorgenson 1969;Kneib 1978;Kneib 1984;Yozzo and Ottman 2003). Since more individuals of F. jenkinsi were collected during the spring and summer months with increased numbers of juveniles, it was suggested that seasonal abiotic cues such as water temperature, salinity, and turbidity may be influencing life history traits like reproduction and spawning.…”

The saltmarsh topminnow (Fundulus jenkinsi) is federally listed as a Species of Concern due to a its rarity, impacts from human activities, and lack of information on its biology and ecology. From 2007 through 2008, we used Breder traps to fish the marsh edge on a falling tide in four regions from Louisiana through the Florida panhandle during winter, spring, and summer periods. Out of 2,108 Breder traps deployed, 661 F. jenkinsi were collected as far east as Escambia Bay, Florida, with Weeks Bay, National Estuarine Research Reserve (NERR), Alabama, yielding the highest F. jenkinsi abundance. Principal component analysis (PCA) was used to ordinate physical-chemical data into two meaningful components: a geomorphic axis (water depth, bank slope, and plant stem density) and a seasonal/spatial axis of species occurrence (water temperature, salinity, and turbidity). PCA showed a higher mean catch-per-unit-effort (CPUE) in environments comprised of low to moderate stem density (<25 stems/0.25 m −2 ), depth (<25 cm), bank slope (<15°), turbidity (<30 NTU), and salinity (<16) coupled with spring and early summer water temperatures (>15°C). F. jenkinsi CPUE was significantly higher in Spartina cynosuroides marsh edge compared with five other habitat types, even though it was one of the least sampled habitats. This species appears to be collected more frequently and in higher CPUE in small dendritic creeks off of main channels than suggested by our previous work in main channel edge habitat. This suggests that small creeks are important vectors for marsh access and supports the value of the dendritic nature of salt marshes to marsh residents.
